APPARATUS FOR HEATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 248,948, dated November1, 1881. Application filed February 18, 1881. (No model.)

1' 0 all whom it may concern Be it known that I, JOHN F. PEAsE, ofSyracuse, in the county of Onondaga, in the State of New York, haveinvented new and useful Improvementsin Apparatus forHeatingBuildings, ofwhich the following, taken in connection with the accompanying drawings,is a full, clear, and exact'description.

This invention relates more particularly to the hot-air furnace forwhich I have obtained Letters Patent No. 192,837, dated July 10,1877.

The object of this invention is to obtain a greater range ofdistribution of heat from said furnace, and adapt the same for heatingextensive buildings and apartments notaccessible by hot-air ducts; andto that end the invention consists, essentially, in the combination,with a case provided with air'iulets at its base and with hot-air ductsat or near its top, of an upright tubular boiler mounted on'a fire-boxand tapped by steam-pipes adapted to be extended through the building tobe heated, a combined radiator and smoke-box applied to the upper endofthe boilerand communicating direct with the boiler-tubes, a radiatorof crescent shape arranged around the exterior side of the boiler, withan air-passage between them, smoke-flues extended, respectively, fromthe smoke-box to the ends of the crescent radiator, exit smokefluesextended, respectively, from the radiator and smoke-box and having adamper for diverting the products of combustion from the direct-exitflue to that connected with the crescent radiator, all combined andarranged in the first-mentioned case substantially in the mannerhereinafter more fully described, and specifically set forth in theclaim, by which arran gement such apartments of the building as cannotbe conveniently reached and heated by the hot-air ducts of the furnacecan be heated by steam-pipes extended from the steam-boiler combinedwith the furnace.

In the accompanying drawings, Figure 1 is a side elevation of myimproved heating apparatus, with aportion of the casin g broken away toillustrate the internal arrangement of the invention. Fig.2 is a frontview of the furnace and boiler; Fig. 3, averticalsection on line 00 m;Fig. 4, a top View of the furnace and boiler, and Fig. 5, ahorizontaltransverse section on line 3 y.

Similar letters of reference indicate corresponding parts.

A represents the lire-pot, upon which I have placed a combution-chamberin the form of a dome, which, by means of flues near itsbase, communicates with a radiator, It, made crescent shape and providedwith an exit smokeflue, as shown in the drawings hereto annexed. Theheat generated by the described furnace is absorbed by the current ofair which is admitted at the base of the case G inclosing the furnace,and the air thus heated is conveyed to the various apartments of thebuilding by ducts H H, extended from the top ofthe case in the usualmanner. Since the extension of said hotair ducts to thevariously-located apartments is frequently difficult, expensive, and invery large buildings almost impracticable, the use of hot-air furnaceshas been limited to warming dwellings of moderate size. To obviate thesedifficulties I combine with the aforesaid hotair furnace a stea m-boilerin the following manner, to wit:

B denotesasteam-boiler, mounted on the firepot A and having verticalflues a a, through which the products of combustion pass direct to asmoke-box, 0, applied to the upper end of the boiler. Said smoke-box hasextended from its sides smoke-flues E E, which are deflected downwardand connected, respectively, with the ends of the crescent-shapedradiator R, which is arranged around the exterior side of the boiler,and with an air-passage between them, and is provided at the rear withan exitflue, 1. The products of combustion from the fire-box A are thuscaused to pass through the flues ofthe boiler B into the superposedsmokebox C, from whence they are conducted to the radiator It, and arefinally allowed to escape through the exit-flue I into the chimney.

F is another exit smoke-flue, by which the smoke-box communicates directwith the chimney, said flue being provided with a damper, by means ofwhich said direct communication can be closed and the products ofcombustion forced to take the circuitous course through the radiator It,before described.

The damper 61 may be opened so as to increase the draft when firststarting the fire. The smoke-box 0 over the boiler B, being impingedupon by the products ofcombustion and deflecting and retarding thecurrent of the same, is thus made to serve as an additional radiator,which augments the heating capacity of the hot-air furnace. Suchapartments of the building as cannotbe conveniently reached by thehot'air pipes H may be heated by steampipes 1), extended in the usualmanner from the boiler to the radiators located in said apartments.

I do not claim, broadly, the combination of a steam-boiler with ahot-air furnace, as I am aware the same is not new; but

\Vhat I do claim as my invention is The combination, with the case Gr,provided with air-inlets atits base and with hot-air ducts H H at ornear its top, of the fire-box A, the upright tubular boiler B, mountedon said firebox and provided with steam-pipes b, the combined radiatorand smoke-box (J, applied to the upper end of the boiler andcommunicating direct with the fines of the boiler, the radiator R, ofcrescent shape, arranged around the exterior side of the boiler with anainpassage between them, the smoke-fines E E, extended, respectively,from the smoke-box O to the ends of the crescent radiator R, the exitsmoke-fines I and F, extended, respectively, from the radiator R andsmoke-box U, and the damper d in the flue F, all combined and arrangedwithin the case Gr substantially in the manner described and shown.

In testimony whereof Ihave hereuntosigued my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 16th day of February, 1881.
